The cosinor model was valid, confirming that melatonin has a circadian pattern of concentration in Echinaster brasilien-sis, with a acrophase at 2147 h and a mesor of 4.79 ng of melatonin/mg of protein (Fig.
In comparison to that observed in the animals under the natural light/dark cycle, the peak of production in the animals kept at constant darkness was a little earlier, at 2035 h, and the mesor was statistically higher (8.09 ng of melatonin/mg of protein; P < 0.0001) (Fig.
value (mean) for men and women volleyball players is 118.38 mm Hg and 117.23 mm Hg, respectively.
By contrast, the mean (95% CI) MESOR
in the obese group was much higher than that in the lean group [210.4 (202.4-219.1) vs 140.4 (135.1-146.8) ng/L; P < 0.01].
